Kahdesti

Kahdesti is a Finnish adverb meaning "twice" or "two times." It indicates that an action or event occurs two times. The form is built from the numeral kaksi (two) with the adverbial suffix -sti, and it is part of a family that includes kolmesti ("three times") and neljästi ("four times").

Usage: Kahdesti is used with verbs to express repetition. Examples: "Kävin kahdesti kaupassa" (I went to the store twice), "Käyn kahdesti viikossa" (I go twice a week). The word is often preferred in casual speech or when a concise expression is desired; in more formal or explicit contexts, Finnish speakers may say "kaksi kertaa."

Nuance: There is a distinction between kahdesti and kaksi kertaa. Both convey two repetitions, but kaksi kertaa is a neutral, explicit construction, while kahdesti is a compact adverb commonly found in everyday language. In some contexts, kahdesti may carry a slightly more idiomatic or spoken-register feel.

Etymology and related forms: Kahdesti is formed from kaksi with the adverbial suffix -sti. Related forms include kolmesti, neljästi, and kaksinkertaisesti (in a twofold manner). The adverb remains uninflected, as is typical for Finnish adverbs.
